+
+ Make Uniscribe optional on nmake win32 builds
+
+ Most of harfbuzz clients don't need Uniscribe and DirectWrite support
+ at all
+ as harfbuzz is a replacement for Uniscribe so Chromium and Firefox
+ are using
+ harfbuzz without them on Windows.
+
+ This removal also helps win32 nmake clients to have reduced binary
+ size and
+ libs count.
